A headache diary

A headache diary - if you keep a diary it may help you identify your headache triggers. When a headache starts write down when it started, include notes of what you drank and ate during the previous 24 hours. Note down how long you had slept, whether it was a good night's sleep, when you slept. Record in your diary what was happening in your life immediately prior to the onset of your headache - were you under unusual stress? Write down how long the headache lasted, and if you can, what made it stop.
